Application December 23, 1954, Serial No. 477,280

2 Claims. (Cl. 259-134) The present invention relates to mixing devices for paint and the like.

The present invention has for its principal object to provide a mixing tool for attachment to an electric drill motor or a similar rotative element for insertion within a can of paint or the like.

Another object of the present invention is to provide a sturdy tool for attaching to the motor of an electric drill for stirring paint, and one Which will not spill or splash the paint upwardly out of the can.

A further object of the present invention is to provide a mixing device which is applicable to mixing food. as well as paint and one having a conformation which effectively mixes materials of high viscosity without spilling or splashing.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawings, in which:

Figure 1 is a side view in elevation of the present invention as attached to an electric drill motor.

Figure 2 is a side view partially in cross section of a mixing tool of the present invention, and

Figure 3 is an end view partially in cross section on line 33 of Figure 2.

Referring in greater detail to the drawing, an electric drill is indicated by the reference numeral and is provided with a chuck 11 to which is detachably secured the upper end 12 of a shank 13, the lower end of the shank carrying an inverted cup member indicated by the reference numeral 16. As shown in Figure 2, the lower end of the shank 13 is formed with a shoulder 14 and a threaded end portion 15.

The cup member 16 which is inverted and of a sub stantial hemispherical shape is provided with a socket 17 intermediately of its boundary, the socket 17 having internal threads which engage the threaded end portion of the shank 13.

The cup member 17 is formed with an upwardly extending flange 18 circumposed about and spaced from the exterior thereof and connected by its lower end to the periphery of the cup member 16, the flange forming with 2 said cup member a circular trough extending about the exterior of said cup member.

The shank 13 is preferably made from drill steel or the like, and the cup member 16 is preferably constructed of: stiif plastic, semisolid rubber, or lightweight metal.

In use, the upper end of the shank 13 is detachably secured to a source of rotative energy such as an electric drill motor, and the lower end of the shank with its attached cup member 16 'is inserted within the container of material to be mixed. It has been found that due to the inverted cup shape of the cup member 16, materials such as paint and other liquids of high viscosity are readily mixed without spilling or splashing, the trough formed by the upturned and upstanding flange 18 with the cup member 16 guiding the liquid upwardly as it is displaced by centrifugal movement from the center of the cup member 16. The inwardly curved upper end of the flange 18 causes the liquid to curve back towards the shank 13 without splashing or spilling outwardly and upwardly from the container.

The mixing tool of the present invention is equally effective in mixing liquid and semisolid foods as well as paint.

While only a single preferred embodiment of the present invention has been here illustrated and described, it is believed that other embodiments may be made and practiced within the scope of the appended claims without departing from the spirit of the invention.

What is claimed is:

1. A mixing tool .comprising an upright shank having its upper end adapted to be connected to a rotative element, an inverted cup member disposed adjacent the lower end of said shank and secured to the latter for rotative movement therewith, and an upwardly extending flange circumposed about and spaced from the exterior of said cup member and connected by its lower end to the periphery of the cup member, said flange forming with said cup member a circular trough.

2. A mixing tool comprising an upright shank having its upper end adapted to be connected to a rotative element, an inverted hemispherically shaped cup member disposed adjacent the lower end of said'shank and detachably secured to the latter for rotative movement therewith, 'and an upwardly extending flange circumposed about and spaced from the exterior of said cup member and connected by its lower end to the periphery of the cup member, said flange forming with said cup member a circular trough.
